So... I've been using the d20pfsrd to look up the pathfinder rules, or using my d&d 3.0e rulebooks. But I can't find any of the starjammer rules in the srd. Are there substitutes that can be used to help figure what to do with these pony spaceships?

The ideas are really cool, and it just so happens that my current d&d campaign is taking place in outer space and on different planets. But I don't want to have to learn (or teach my DM) another whole new ruleset (he uses d&d 1e, ad&d core rules supplemented with stuff from the newer editions, but we only have the books up to 3.0) when we might only be using them for this one campaign. Any advice?
